PCM Cooling Pack

for Cold Chain & Thermal Control Applications

PCM cooling pack

What Is a PCM Cooling Pack?

  • A PCM cooling pack is a thermal control product filled with phase change materials (PCMs) that absorb and release heat at a predefined temperature. Unlike traditional ice packs, PCM cooling packs maintain a stable temperature range for extended periods, making them ideal for cold chain logistics, temperature-sensitive transport, and thermal protection.
  •  
  • PCM cooling packs can be designed for specific temperature ranges, including sub-zero, refrigerated, and controlled room temperature applications.
  • Weight: 150g
  • Size(mm): 140 x 120 x 15
  • PCM: -21°C/-18°C/-11°C/-5°C/0°C/5°C/15°C/18°C/20°C/23°C/25°C/28°C

How PCM Cooling Packs Work

PCM cooling packs operate based on the latent heat storage principle. During the phase change process, the PCM absorbs or releases large amounts of thermal energy while maintaining a near-constant temperature.

Key working stages:

  • Charging (freezing or conditioning at a set temperature)
  • Phase change heat absorption or release
  • Temperature stabilization during transport

Key Features of PCM Cooling Packs

  • Precise temperature control
  • Long-lasting cooling performance
  • Reusable and durable design
  • Customizable PCM formulation
  • Safe and non-toxic materials

  • How To Use?
  • Foam Brick PCM Packs​ should be used along with insulation shipping boxes.
  •  
  • ①Pre-cooling Preparation: Before use, place the PCM pouches/Gel Packs in a for a certain time to ensure complete freezing;
  • ②Placement Method: Evenly lay the frozen pouches on the bottom and surrounding inner walls of the insulated container, ensuring all surfaces of the container are fully covered to form a full-wrap insulation protection;
  • ③Cargo Placement: Put the goods in the center of the insulated container, then place the PCM pouches/Gel Packs on top of the goods, and close the insulated container;
  • ④Extension of Cooling Duration: If it is necessary to extend the transportation time, additional PCM pouches/Gel Packs of the corresponding quantity can be added on the existing basis, or larger-sized products can be selected;
  • ⑤Reuse: After use, wait for the cold storage bag to thaw naturally, wipe off surface stains, and it can be reused after re-freezing.
